CEO Zach Kaplan says the inspiration comes from the success of the Chicago Public Library’s Maker Lab, winner of the Social Innovator Award at the 2013 Chicago Innovation Awards. His company says it also wants to build the market for its 3D carving machines.

Kaplan, who often refers to what he calls the coming “third industrial revolution” of small manufacturers, plans to announce the giveaway Wednesday at San Francisco’s MakerCon, Inventables said in a statement. MakerCon is an annual conference and workshop for the growing maker community.
